I have worked in partnership with the boys at JSAR and developed an amazing new option for the Umarex Gauntlet. It is the externally adjustable regulator which allows the user to raise or lower the output pressure of the regulator on the fly. No degassing, not funky procedures other than turning the cogged adjuster wheel. I developed two configurations for the Gauntlet and they come to two flavors.
Available configurations:
1) For the .177/.22 Caliber I have selected 500 to 1500 PSI range
2) For the .25 Caliber I have selected 1400 to 2400 PSI range
Here is a .22 Caliber Gauntlet with it installed. You can see both gauges without making any modifications to the stock or forearm cover.

Below is a photo of the radar results of the .22 Gauntlet shooting two shots with the regulator adjusted to 1100PSI and a second set of two shots with the regulator turn all the way up to 1500PSI (again that is max for the .22 version but the .25 caliber version can be adjusted to a maximum of 2400).

A Gauntlet with the Super Tune Kit and a JSAR Flex Reg will amazingly tunable. I will be making an installation video for this as well as it being demonstrated on the .25 caliber as well.
HUGE possibilities!
Thank you

oh the possibilities with this addon...keep up the awesome work hajimoto.

I was wondering about this direction with our Gauntlets....did you change out he gauges to fit in .25 Cal?
My Haj tune is shooting so well with your reg bump to 2100 PSI and tune kit and new spring on Hammer I hesitate to do anything at all to it!

What this will offer you is the ability to fly larger heavier ammo like slugs or hybrids. You can set the reg to any pressure setting you want for the .22's from 500 to 1500 PSI or for the .25 from 1400 to 2400 PSI. In the case of the .25 caliber that means you can keep the regulator at 2100 PSI and when or if you want to sling a Hybrid for instance you can simply crank up the regulator and tweak the hammer energy with the STK that is installed.
This honestly take the Gauntlet to a level of tunability that only $1200 plus airguns possess.

Not to be the nay sayer ... requirements in hammer weight and spring energy differ GREATLY with changes in operating pressure.
While one can change the power via pressure easy enough ( this is major cool BTW ) sadly the valve dwell with vary wildly with much suffrage in efficiency when tuned outside of the sweet spot in pressure / hammer strike energy on the poppet valve.
The adjustable regulators are indeed a MAJOR step in the right direction, but also need to be managed easily with a viable system in changing hammer energy delivered to valve that's not caught up just yet.

My buddy(Mike Kobel-Citrus airguns) made me a setup for my Gauntlet similar to Marauder setup with integrated HS adjuster & stroke adjuster( had to add short screw top & bottom for access thru endcap for adjustment( with new endcap) but with this setup should be able to use in tandem with adjustable reg.
-
Great work Haj. I do not have a Gauntlet but it seems that with guys like you they are becoming very mod-able just like the marauders. There is nothing more satisfying than to take a rifle to the whole next level. Keep up the good work.
-
Hajimoto,
So how are these new flex regs holding up? Do they have a tendency to creep? Are they stable? I'm looking to get one very soon for my .25 gauntlet. Can't wait for the video to come out on them. So which gauge is pointing at the barrel, is it tank pressure?
Just purchased a .38l bottle with the proper threads. Gonna take a bit for it to arrive but should really boost shot count. So I'll only need the regulator.

Scott you are 100% correct and I guess I take it for granted that every Gauntlet owner have installed a Super Tune Kit. I have said this 1 million time before that any Gauntlet owner that is looking for ANY type of adjustability so they can fly different weight projectiles at their most stable rate of travel, MUST have some sort of hammer preload adjustment and the STK gives that to the end user.
Thanks for reminding me that where I am in process may not be where the new guy to this experience will be.

Hey Dan,
These Flex regs have been rock solid with no creep. It is important to note that as Motorhead and I discussed in the previous post, hemmer preload energy adjustment is a must so in order to get true consistent results you need to have the Super Tune Kit installed. I still have some left but with Ninja Paintball shut down I am quickly running out of items that I normally have access to.

Whats the availability of these regulators?
Do you have them in stock or does it come from jsar?
Can ya have one from 1900psi to 2900psi soon?
-
Yeah, i already have the stk in mine. so i'm all set there. gonna put my order in today or tomorrow for one of the regs.

JSAR only has been buying quantities from NINJA to stay up with production / assembly requirements and honestly IMO looked to be shy of being able to sell them alone to non raptor customers. Having them to sell because you wish to have one I did not see much of, tho the 5/8 threaded version sold out quickly and few 18mm too. In this current climate Certainly Not with ninja shut down.

my reg is ordered

Can you share his phone number pls?

Haj,
Any chance trying the Gauntlet at the lowest pressure setting on the .22 ? Want to see if it can go to about 600 fps for indoor practice. Thanks.

I hit that with stock 1700 psi when adjusting my stk in the ,25 cal. So don't see why it couldn't be done on .22

If you have the STK installed, you can reach that speed by backing out adjuster without changing output pressure ie. When 1st installed, first shot out was 430 fps with stock reg on .22 @ 1450 output, before turning in HS adjuster- lucky it came out the barrel LOL

He nailed it! If you have an STK you can lower the output to almost nothing.

ok so my new larger bottle will be here in the next few days. Looking over the flex regulator. i noticed a big issue with these setups. the output gauge reads to 6k psi. this is senseless. should only have a 3k psi gauge on the output for better resolution when setting out put. the way they are currently one would have to have a an external tester to dial in as the resolution is not fine enough as is. One would basically be guessing on the output set point.
I'm sure its a micro gauge. but what size and thread would i need to find to replace the 6k gauge with a 3k gauge so it would work and adjustments can be made more precise?
-
1/8-27 NPT
-
awesome. so this gauge will work just fine for me then,

I could not agree with you more and in very detailed conversations with Ray at Ninja I requested 3k gauges from day one. They started importing large quantities of these gauges but were hit by the huge delays associated with COVID-19 and China.
The manufacturer/exporter shut down and there were shipments going out. So because I sell so many Flex Regulators and while my need for 3K gauges was real, my quantities are far less than that of Ninja.
I found the perfect black faced 3K gauges and ordered 30 or so and that was over 2 months ago :(
I am in contact with the vendor but am losing faith that they will ever arrive. On my personal Flex Reg configurations, I have out fitted them with EDGUN EDMU's
The final piece to this puzzle is the follow up with customers who already own the 6K gauges and educating them on the final to arrive 3K gauges. We all know that will be met with "Well if I send you back the 6K, can you just swap for the 3K?"
While Ninja would still have use for the 6K gauge, Hajimoto Productions would not so I'm waiting for COVID-19 to back off, Ninja to get back up and running and then trying to close the 3K/6K gap.
-
sounds logical with all the delays covid-19 is causing. the gauge i found came in. but it slightly larger than the ninja one. i haven't swapped it in yet as i'm concerned it may hit the guard. wasn't sure and thank you for the background info on the gauge with the 6k gauges. I just thought i'd point it out ans it didn't make sense to me being that way.

Following this thread.
I hope Everyone is doing the best they can given this virus mess.

just found an issue with my foster fitting on my flex reg leaking. it is from the inside of this fitting, not where the fitting goes into the regulator. i went to put a few drops of oil in and noticed bubbles. can these be rebuilt of does the foster fill fitting need to be replaced altogether?
i thought i was losing air, but thought it was just my imagination. low and behold it is. kinda odd, as i fill from a yung heng compressor. so top offs are no issue for me.

I could be wrong, but I think there's an o-ring in the fill nipple...
-
should be. As it is basically a one way check valve fill fitting.
-
Here is a trick I use a lot. Take a hard 1 1/2" to 3" rod that is about 1/8" in diameter like a nail, pop rivet or section of drill rod. Place the rod inside the foster fitting so it is all the way in take something hard but but not heavy. Something like a 3/4" wrench or you can use a pair of channel lock pliers.
While the rod is in the foster fitting you just tap the rod end with the wrench or pliers and and you will hear the poppet in the fost fitting snap some air and typically it will align correctly and stop leaking.
